Definitions
- Embodiments of the present invention relate to an underwater sliding member, a method for manufacturing an underwater sliding member, and a hydraulic machine.
- sliding members of hydroelectric generators are lubricated with oil, but application of water-lubricated bearings is required due to environmental problems of river pollution caused by oil spills.
- the sliding member of the water-lubricated bearing includes a base material made of a metal material, an intermediate layer having a porous structure joined to the base material and made of a metal material, and a slide made of a resin material formed on the intermediate layer. Having a dynamic layer.
- the intermediate layer of the sliding member is formed of a plurality of spherical members made of a metal material on the main surface of the base material so as to be bonded to the main surface, thereby forming a porous structure.
- the shape of the pores of the porous structure constituted by a plurality of spherical members is anisotropic.
- the problem to be solved by the present invention is an underwater sliding member capable of suppressing deterioration of mechanical properties over time even when used in an underwater environment for a long time, and an underwater sliding member manufacturing method, As well as providing a hydraulic machine.
- An underwater sliding member is an underwater sliding member used in water, and includes a base material made of a first metal material and a porous structure joined to the base material and made of a second metal material.
- FIG. 1 is an external view showing a schematic configuration of an underwater sliding member in the present embodiment
- FIG. 2 is a cross-sectional view showing a schematic configuration of the underwater sliding member in the present embodiment.
- an underwater sliding member (hereinafter sometimes abbreviated as “sliding member”) 10 of the present embodiment includes a base material 11 made of a first metal material, and the base material. 11, a porous intermediate layer 12 made of a second metal material, a corrosion prevention layer 122 (corrosion current blocking layer) formed on at least the intermediate layer 12 and having electrical insulation, and at least corrosion.
- the sliding layer 13 is formed on the prevention layer 122 and is made of a resin material containing a conductive filler, and the pores of the porous structure of the intermediate layer are filled with a part of the resin material. Yes.
- the resin material of the sliding layer 13 contains a conductive filler such as carbon fiber from the viewpoint of improving mechanical properties.
- a member denoted by reference numeral 15 indicates a sliding surface of a shaft on which the sliding member 10 slides, whereby the sliding member 10 in the present embodiment functions as a bearing.
- the intermediate layer 12 is formed such that a plurality of spherical members 121 made of the second metal material are bonded to the main surface 11A on the main surface 11A of the base material 11.
- the intermediate layer 12 forms a porous structure by arranging a plurality of spherical members 121 along the main surface 11 ⁇ / b> A of the substrate 11 via the first holes 121 ⁇ / b> A.
- bonding with respect to 11 A of main surfaces of the base material 11 of the spherical member 121 can be performed by the method (brazing joining method) using the brazing material demonstrated below, or a solid phase diffusion joining method, for example.
- Part or all of the spherical member 121 may be a fibrous member.
